Siemens SQN13.170B9 actuator

Siemens SQN13.170B9 actuator: precise air damper control for small and medium power burners. Buying Siemens SQN13.170B9 means equipping your burner unit with a reliable, compact, and high-precision electric drive for air supply regulation. This model is widely used in combustion control systems for gas and oil burners, ensuring an optimal fuel-air mixture ratio, which directly affects efficiency, fuel savings, and equipment safety. Purpose and application area The Siemens SQN13.170B9 actuator is designed for automatic positioning of air dampers in small and medium power burner devices. It operates under the control of a burner manager (burner automation) and provides precise damper movement in various operating modes: Ignition — air supply in the amount necessary for safe ignition; Low power operation — maintaining stable combustion at partial load; High power operation — full damper opening for maximum output; Combustion chamber purge — damper opening before ignition to remove residual gases. The actuator is compatible with combustion automation LAL, LOK, LFL, LGK, LME, as well as modern electronic burner managers LMV2 and LMV3.
